Purpose

Create and use de-identified databases for research.

  • Anonymises relational databases.

  • Extracts and de-identifies text from associated binary files.

  • Performs some specific preprocessing tasks; e.g.

    • preprocesses some specific databases (e.g. Servelec RiO EMR);

    • drafts a “data dictionary” for anonymisation, with special knowledge of some databases (e.g. TPP SystmOne);

    • fetches some word lists, e.g. forenames/surnames/eponyms.

  • Provides tools to link databases, including via Bayesian personal identity matching, in identifiable or de-identified fashion.

  • Provides a natural language processing (NLP) pipeline, including built-in NLP, support for external tools, and client/server support for the Natural Language Processing Request Protocol (NLPRP).

  • Web app for

    • querying the anonymised database;

    • providing a de-identification API;

    • managing a consent-to-contact process.
